A super-accurate atomic clock just got more accurate. Thanks to new modifications, a record-setting strontium atomic clock is now so stable that it could theoretically "tick" for 15 billion years — the age of our entire universe — without gaining or losing a second. That's much more accurate than America's master clock.

The clock was developed by JILA, a joint institute of the US National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. Its new capabilities are reported in a paper published on Tuesday in Nature Communications.
